Cancer in first degree relatives of Latin American women with cervical cancer. A pilot study.

Background: Cervical cancer is the most frequent cancer of women in Latin America, being strongly associated with infection by certain human papillomavirus (HPV) types. Familial cancer clustering can be due to interactions between infectious agents and host genes.

Materials And Methods: A cancer-related family history of first degree relatives was elicited in 335 women with invasive cervical cancer (probands) and in 335 women without cancer (controls) in Honduras, Peru and Uruguay, and the frequency of reported familial cancers among the relatives was compared between proband and control relatives.
